Whats up with Jordan?

Jordan is really a funny kid. He is always doing or saying something that makes you laugh. In school if he wasn't so shy he would have been the class clown. Its just here lately he has been making commets about me that are not true. I just don't know where he would come up with what he is saying. He's always laughing when he says it, so I think he thinks its funny. He will be cutting up with us and just bamb out of the blue tell Jeff that I have boyfriends come over all the time. Jeff knows its not true, but it really bothers me that my son finds this humor funny. I think maybe he gets the idea from Jeff, cause I always ask him if he is going to be home . Jeff always says why your boyfriend coming over. So maybe thats where Jordan is getting it. I don't like it. The next time he says it, I'm going to let him know how disturbing that is.
